Answer:
They take the form of heat.
Explanation:
Electromagnetic waves with wavelengths greater than 750 nm are infrared light.
They are not visible to human eyes, but we can feel them as heat on our skin.
B is wrong. It is UV light that causes skin cancer and sunburn.
C is wrong .Visible and UV light have shorter wavelengths.
D is wrong. Human eyes cannot see IR radiation
I’m going to assume here that you meant “plants”.
Animals rely on plants as a source of food. Herbivores way plants to survive and carnivores eat the herbivores to live.
Now plants rely on animals because their scat fertilizes the plants, helping them grow and survive longer.
Barrier islands typically have sand in the beach zone and dune field, and mud in the back-barrier. Overwash deposits sand in the back-barrier.
Barrier islands form in three ways. They can form from spits, from drowned dune ridges or from sand bars. Longshore drift is the movement of sand parallel to the shore caused by the angle of the waves breaking on the beach. ... When a storm such as a hurricane digs an inlet through the spit a barrier island is formed.
Answer: Saturated
A solution that contains the maximum amount of solute that is soluble at a given temperature is said to be saturated.
Explanation:
A Saturated solution is one that contains as much (i.e maximum) solute as it can dissolve at that temperature in the presence of undissolved solute particles.
For instance: if a given volume of water can only dissolve a certain amount of salt in it at room temperature, then, more salt added will not dissolve.
Thus, making the solution saturated.
Answer:
Balance chemical equation is
O2(g) + 2H2(g) --> 2H20(g)
a. 0.20 mol 02 --> 0.225mol H20
b. 0.30 mol H2 --> 2.7mol H20
